Switchgear with a vacuum switch chamber for loading, isolating, grounding and protecting against overload and short-circuits includes movable contact stems with movable contacts under pressure from a disconnecting spring.

摘要

A swiveling vacuum chamber (SVC) (30) moves from a turn-on position with a fixed turn-on contact into a central disconnecting position and into a grounding position with an associated fixed grounding contact and back. A first movable contact stem (36) has a first movable contact (38) under pressure from a disconnecting spring. A curved path on the fixed grounding and turn-on contacts picks up the movable contact stem and presses against a second contact (39) in the SVC.
